About Middlesbrough
On the south bank of the River Tees, Middlesbrough grew rapidly during the Victorian era through its iron and steel industries. Today its mix of period terraces, post-war semis, riverside homes and modern developments calls for home improvements that complement local architecture and character.
We help homeowners choose frame styles, colours and glazing options to suit brick, render and stone finishes — from traditional Victorian terraces in Linthorpe and Gresham to larger detached homes in Nunthorpe and Marton and contemporary properties in Coulby Newham and Hemlington.
